A. HOFFMAN AND H. TV. LIMEBEOK, OF HALF DAY, ILLINOIS.

Specification forming part of Letters Patent No. 33,740, dated November19, 1861.

To all whom it may concern:

Be it known that we, A. HOFFMAN and H. W. LIMEBEOK, of Half Day, in thecounty of Lake and State of Illinois, have invented certain new anduseful Improvements in Cultivators; and we do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, and to the letters of refereneemarked thereon, in which Figure 1 is a side elevation; Fig. 2, acrossvertical section, and Fig. 3 a plan View.

The nature of our invention consists in the combination and arrangementof certain devices, the peculiarities of which will be hereinafter fullyset forth.

To enable others skilled in the art to make and use our invention, wewill now describe its construction and operation.

A represents the frame, more fully shown in Fig. 3.

b b b are a series of teeth secured to crosspiece a.

0 represents a seed-box, which should be provided with-the apertures e ee.

d is a slide for the purpose of suspending the operation of the seedingapparatus when desirable.

g g represent a couple of slots in the bottom of the seed-box, throughwhich pass the headed bolts or pins 7t h. Thus the box 0 will oscillatewhen operated upon in a manner hereinafter explained.

B represents a driving-wheel, and k a camwheel, bot-h arranged upon thesame shaft.

f is a bent lever attached to the seed-box O, and working on a pivot at0. The lower and rear endof this lever is bent down at a right angle andslotted at Z, so as to form a fork for the cam-wheel k to work in, as isshown in red lines, Fig. 1. 0 is the fulcrum of lever f. Thus it will beobserved that as the camwheel revolves the lever will impart anoscillating motion to the seed-box.

E represents a curved harrow or rake,which is attached to the beams mmby means of the connecting-pieces pp. Said pieces are loosely bolted tothe beams in order to allow of the harrow E being taken up or suspendedat any time.

q q represent two plows attached to beams on m. w w are also two plowssecured to beams to a. It must be particularly observed that these plowsshould turn to the right and left, according to the sides upon whichthey are placed. Thus upon the right side they must turn to the right,&c.

The operation of our machine is as follows: Should it be desirable tosow small grain, the slide d is elevated and the machine is put inmotion. The cam-wheel, revolving, imn1e= diately acts upon the lever, asalready de scribed, and a zigzag or oscillating motion is imparted tothe seed-box, which, being agitated, causes the grain to be distributedequally over the surface of the ground.

The operation of the seeding apparatus may at any time be suspended bysimply closing the apertures by means of the slide.

Having thus fully described our invention, what we claim, and desire tosecure by Letters Patent. is

The seed-box O, cam-wheel k, lever f, harrow E, teeth I) b l), and plowsq q and w w, when all are constructed and arranged substantially in themanner and for the purpose set forth.

In testimony that we claim the foregoing, we hereunto set our hands inthe presence of the following witnesses.
